WPF数据绑定:如何访问“父”数据上下文?
我有一个窗口中包含的列表(见下文)。窗口DataContext有两个属性,Items和AllowItemCommand。
如何获取针对窗口的属性需要解析Hyperlink的Command属性DataContext?
<ListView ItemsSource="{Binding Items}">
<ListView.View>
<GridView>
<GridViewColumn Header="Action">
<GridViewColumn.CellTemplate>
<DataTemplate>
<StackPanel>
<TextBlock>
<!-- this binding is not working -->
<Hyperlink Command="{Binding AllowItemCommand}"
CommandParameter="{Binding .}">
<TextBlock Text="Allow" />
</Hyperlink>
</TextBlock>
</StackPanel>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
</GridView>
</ListView.View></ListView>BIG阳
